and your point is?
A civillian pilot of a non Mil registered a/c does not require any permission at any time to enter a MATZ unless the MATZ is part of a class A, B or D controlled airspace.
That may be so but it is pretty poor airmanship to do so, and can cause significant aggravation and unneccessary risk. Entering the inner ATZ uncleared would certainly result in fallout. MATZs exist for very good reasons and most military controllers will bend over backwards to accommodate a civvy MATZ crossing if they have the courtesy to talk on the radio. Loitering around within a MATZ doing GH, PFLs etc uncleared is not particularly bright.
To turn it around, it would be legal for 4 C-17s to continuously fly a 3nm circle around your home GA aifield's ATZ all day between 250 and 2000ft while an 8 ship formation of Chinooks hovered in the overhead at 2050ft. Legal - yes. Good airmanship, courteous, safe etc - no.
